A Case of Mistaken Identity

New Dinosaur Identified at Garden of the Gods

On May 24, 2008 Garden of the Gods Visitor & Nature Center announced the world's only known fossil of an entirely new dinosaur species, Theiophytalia kerri. Theios is of Greek origin, meaning "belonging to the gods" and phytalia means "garden." kerri honors the name of the scientist who first discovered this 125 million year old skull in Garden of the Gods Park.

In 1878, Professor James H. Kerr of Colorado College discovered what he believed to be "portions of 21 different sea monsters" in the Garden of the Gods Park. Kerr wrote of his discovery to associates back east which caught the attention of O.C. Marsh, the famous dinosaur paleontologist from Yale University. In 1886, Marsh came to Colorado Springs and obtained the fossil skull, identified it as a Camptosaurus dinosaur, and shipped it to the Peabody Museum in New Haven, Connecticut.

For one hundred and seventeen years, Dr. Kerr's dinosaur fossil was forgotten. In 1994, the new Garden of the Gods Visitor Center was under construction. When geology exhibits were being created for the center, the Denver Museum of Nature & Science was consulted about a dinosaur exhibit. Dr. Kirk Johnson and Dr. Ken Carpenter surprised the city park staff with information about the Camptosaurus skull found in the Park.

Kirk Johnson hand carried the dinosaur fossil from Yale to Denver so that Ken Carpenter could study the ancient dinosaur skull and make a precise replica (cast) of it. In 1997, the Denver Museum of Nature & Science gave a cast of the Camptosaurus skull to the City of Colorado Springs to be exhibited in Garden of Gods Visitor & Nature Center. It was a rare gift, with an ancient and modern story, but the surprise ending was yet to come.

For more than ten years, the dinosaur known as "Campi" had been part of the Jurassic exhibit. But, from the time he made the replica, Dr. Carpenter had his doubts about this dinosaur's true identity. In 2006, Dr. Carpenter along with his associate, Kathleen Brill, published a paper that resolved irregularities in the attributes of that skull and its camptosaur heritage - the shape and length of the skull and snout, and the position and shape of nasal and eye-socket openings. Those variations, plus issues with the soils originally embedded around the fossil, have resulted in the designation of the first and only Theiophytalia kerri.

The new Cretaceous period Theiophytalia kerri is thus determined to be a new species of dinosaur, the only one known in the world and "belonging to Garden of the Gods."

Timeline

1878 James Kerr, geology professor at Colorado College, finds a fossil skull "in one of the ridges of the Garden of the Gods."

1886 O.C. March, famous 1800's dinosaur collector from Yale University, obtains the fossil skull from James Kerr, identifies it as a Camptosaurus and sends the fossil to the Yale Peabody Museum.

1886-1995 The dinosaur fossil skull safely rests in the Yale Museum, but is forgotten in Colorado Springs.

1994 Colorado Springs City Park Staff research new exhibits for the Garden of the Gods Visitor & Nature Center set to open in 1995.
